| From | Sasha Levin <> | Subject | [PATCH AUTOSEL 4.14 058/115] cpu/SMT: State SMT is disabled even with nosmt and without "=force" | Date | Tue, 12 Nov 2019 20:55:25 -0500 |

From: Borislav Petkov <bp@suse.de>
[ Upstream commit d0e7d14455d41163126afecd0fcce935463cc512 ]
When booting with "nosmt=force" a message is issued into dmesg to confirm that SMT has been force-disabled but such a message is not issued when only "nosmt" is on the kernel command line.
Fix that.
